||'For his independent origination of the theory of the origin of species by natural selection.'
||'On account of his important contributions to the progress of systematic botany, as evidenced by the "Genera Plantarum" and the "Flora Indica"; but more especially on account of his intimate association with Mr. Darwin in the studies preliminary to the "Origin of Species".'
||'For his researches in comparative anatomy, and especially for his intimate association with Mr. Darwin in relation to the "Origin of Species".'
||'For his work on the quantitative treatment of biological problems.'
||'For his long-continued and highly important work in zoology all of which has been inspired by the spirit of Darwinism.'
||'For his numerous contributions to the exact study of heredity & variation contained in "Hereditary Genius", "Natural Inheritance", and other writings.'
||'For his important contribution to the theory of organic evolution by his researches on variation and heredity.'
||'On the ground of the significance and extent of his experimental investigations in heredity & Variation.'
||'On the ground of his eminent services in support of the doctrine of evolution by means of natural selection.'
||'On the ground of his researches in heredity.'
||'For his valuable work in zoology and more especially his researches on heredity and cytology.'
||'As one of the three independent discoverers of Mendels publications; and for his distinguished researches in genetics.'
||'In recognition of his outstanding contributions to the development of biology.'
||'In recognition of his distinguished contributions to the theory of natural selection, the concept of its gene complex and the evolution of dominance.'
||'In recognition of his initiation of the modern phase of the study of the evolution of living populations.'
||'In recognition of his distinguished contributions to the study and theory of evolution.'
||'In recognition of his distinguished contributions to general evolutionary theory, based on a profound study of palaeontology, particularly of vertebrates.'
||'In recognition of his distinguished and extensive contributions in the field of invertebrate zoology and to our understanding of general biological phenomena.'
||'In recognition of the basic concepts he has contributed to the study of animal ecology which, with his foundation of the Bureau of Animal Population, have had international impact.'

||'Distinguished for his work on molecular evolution, in particular on the role of stochastic events in determining the rate of evolution.'
||'In recognition of his analysis of pattern formation during insect segmentation, and of his contribution to understanding how genetic processes specify spatial information.'
||'In recognition of his leadership in the study of genome analysis with the potential to have a profound impact on the whole of biology.'
||'for his major and extensive contributions to evolutionary biology, characterised by the application of sophisticated mathematical analysis but focussed on developing biological understanding rather than mathematical niceties.'
